Air spray explosion type soil deep loosening and deep application device

Abstract

The invention discloses an air spray explosion type soil deep scarification and deep fertilization device. The air spray explosion type soil deep scarification and deep fertilization device comprises a compressed air generation device, an airflow spray explosion and energy storage device and a scarification and fertilization gun; the airflow spray explosion and energy storage device is communicated with the compressed air generation device in an on / off manner, is used for storing compressed air and can spray and explode in a high pressure to generate spraying airflow; the scarification and fertilization gun is communicated with the airflow spray explosion and energy storage device and is inserted into the underground to guide the high-pressure spraying airflow into the soil; the air spray explosion type soil deep scarification and deep fertilization device further comprises a fertilizer pumping and transporting device; the fertilizer pumping and transporting device is communicated with the scarification and fertilization gun in the on / off manner, and the spraying airflow entering in the scarification and fertilization gun generates negative pressure for the fertilizer to absorb the fertilizer when the fertilizer pumping and transporting device is communicated with the scarification and fertilization gun. The air spray explosion type soil deep scarification and deep fertilization device solves the problems of deep scarification and deep fertilization of the oil and long-distance transportation of powdery fertilizer, is suitable for large-scale cultivation of plains, and is also suitable for dispersed plots such as mountainous areas and hills; furthermore, the powdery fertilizer conveying system is convenient to move; soil compaction is avoided; big transportation amount is achieved; the deep scarification system has low requirement on power, is small in volume, light in weight and low compaction for soil, and can enable fertilizer powder to be mixed with soil efficiently.

Description

technical field [0001] The invention relates to the field of soil subsoiling, in particular to an air spray explosion type soil subsoiling deep application device. Background technique [0002] Existing soil mechanized subsoiling technology is to use high-horsepower tractors to drive the plowshares to move laterally to loosen the soil, break the bottom of the plow, and deepen the plowing layer, while the deep application of silty fertilizers sweeps the fertilizer granules in On the ground surface, use a rotary tiller or tractor to rotate or plow into the soil. There is no mobile soil deep loosening and deep application related technology and its complete set of equipment. [0003] There are some technical deficiencies in the above subsoiling and deep fertilization methods. First, the technology is single and cannot be carried out in a complete set. Fertilization, soil loosening, and mobile silt fertilizer transportation are carried out separately, and integration has not bee...

AI Technical Summary

Problems solved by technology

[0002] Existing soil mechanized subsoiling technology is to use high-horsepower tractors to drive the plowshares to move laterally to loosen the soil, break the bottom of the plow, and deepen the plowing layer, while the deep application of silty fertilizers sweeps the fertilizer granules in On the surface of the ground, use a rotary tiller or tractor to rotate or plow into the soil. There is no mobile soil deep loosening and deep application related technology and complete sets of equipment

[0003] There are some technical deficiencies in the above subsoiling and deep fertilization methods. First, the technology is single and cannot be carried out in a complete set. Fertilization, soil loosening, and mobile silt fertilizer transportation are carried out separately, and integration has not been realized; second, the application range is small. It can only be applied to cultivated land with good conditions for large-scale farming in plains, and is not applicable to mountainous areas, hills, scattered plots and greenhouses; third, the application of crop species is single, and it is only applicable to annual field crops, and it is powerless to cultivate and loosen soil for perennial economic crops; Fourth, it requires a lot of power and has strict requirements on the basic conditions. It needs to be driven by a large tractor, and the supporting conditions for the foundation are relatively high. Fifth, it has serious damage to the soil. Large-scale machinery can compact the soil and make it harden again. At the same time, the loosening of the soil may damage the soil. granule structure, thereby destroying the cultivated layer
